[Quantitative measurement of 59Fe-absorption. Comparison between iron labelled Parkevit-Fe and an iron-mono-preparation using a wholebody counter (author's transl)].
The intraindividual bioavailability of two iron preparations, resistant to gastric juice, was investigated in 6 healthy volunteers (3 women, 3 men) at the age of about 50 years. They got 59Fe++ labelled preparations. A wholebody-counter with 3 NaJ(T1)-detectors (5 x 4") was used to measure the 59Fe-absorption. 14 days after application the control-preparation showed an 59Fe++-absorption of 1.7 mg and the test-preparation (Parkevit-Fe) showed an absorption of 2.2 mg. This is 100% more than the daily nutritional absorption = 1 mg.
